hello gentlemen
i'm running vsphere data protection 6.1 on ESX 5.5 on a Cisco UCS B200 M3 server.
it co-exists with about a dozen other low demand virtual machine workloads.
The vSphere Data Protection OVA appliance was deployed with the default hardware requirements and backs up to a 12 TB SAN volume on a fairly high performance IBM DS3500 SAS SAN.
all the storage performance tests checked out OK.
I'm backing up around 40 VMs overnight in an overnight 12 hour window.
Backups are configured with the default retention periods.
After installation the backups ran great for the first few months.
But then I started seeing more frequent backup failures or sometimes nothing gets backed up.
I noticed that very often the VDP services spontaneously stop and the backups fail or are incomplete i.e. VM snapshots not cleared.
I can restart services both from the console using "dpnctl start all" or from the VDP-configure web console.
But shortly thereafter many services will stop again especially when they are actually started to do something that previously failed.
this especially includes running integrity checks so that i wind up going several months without a complete integrity check.
also i note that the CPU often gets maxed out at 10 to 12 GHz sometimes.
I have not had any luck in the past year trying to get VDP backup to work reliably.
can anyone tell me what I might be doing wrong ?
with thanks from sunny Vancouver Canada....
